Portlanders jogging and biking the Leif Erikson trail in Forest Park Saturday came upon a perplexing sight: a white antelope with curved black horns loose on the trail.

A male scimitar-horned oryx named Yellow Nose escaped through an open gate and roamed Forest Park on Oct. 24, 2015. The animal's owner, Reed Gleason, captured Yellow Nose and took him home.
